This morning, bluetooth audio output in the native Teams client for Linux
became silent. It worked last week.
I have rebooted inbetween, due to zypper updates.

Other pulseaudio programs work fine, but a test call in Teams yields this in
journalctl --follow:

Bluetooth: hci0: SCO packet for unknown connection handle 257
Bluetooth: hci0: urb 000000001d57a72c submission failed (90)
Bluetooth: hci0: sending frame failed (-90)
Bluetooth: hci0: urb 000000001d57a72c submission failed (90)
Bluetooth: hci0: sending frame failed (-90)
Bluetooth: hci0: SCO packet for unknown connection handle 257

I can only test with bluetooth audio on Leap, because only Tumbleweed
recognizes the audio jack on this machine (HP Elitebook 840 G6).
With Teams and bluetooth, this symptom usually means you have to restart Teams
after connecting a bluetooth headset and set it in HFP mode, but that is
apparently no longer enough.
